鼠标移动速度太快,无法捕获事件

这与:a previous question

有关

但问题是我的代码只有当我在TableLayoutPanel周围移动鼠标时才会失败。

由于鼠标快速移动,C#或Windows是否可能无序地报告/触发事件?

如果是的话,我该如何纠正呢?

谢谢你。我希望这不是双重发布。如果是的话,道歉。

鼠标不会通过它传递的每个像素报告其位置,报告之间的间隔为20毫秒。如果您设法在此时间间隔内跨越控件,则根本不会捕获任何鼠标事件。

我解决了这个问题。这是重新安排逻辑流程的问题。

解决方案跨越3个鼠标事件MouseEnter,MouseMove,MouseLeave。

    private PictureBox HomeLastPicBox = null;

    private TableLayoutPanelCellPosition HomeLastPosition = new TableLayoutPanelCellPosition(0, 0);

    private void HomeTableLayoutPanel_MouseMove(object sender, MouseEventArgs e)
    {
        PictureBox HomeCurrentPicBox = (PictureBox)(HomeTableLayoutPanel.GetChildAtPoint(e.Location));

        if ((HomeCurrentPicBox != HomeLastPicBox) && (HomeCurrentPicBox != null))
        {

            HomeLastPicBox = (PictureBox)HomeTableLayoutPanel.GetControlFromPosition(HomeLastPosition.Column, HomeLastPosition.Row);

            if (GameModel.HomeCellStatus(HomeLastPosition.Column, HomeLastPosition.Row) == Cell.cellState.WATER)
            {
                HomeLastPicBox.Image = Properties.Resources.water;

            }

            TableLayoutPanelCellPosition HomeCurrentPosition = HomeTableLayoutPanel.GetCellPosition(HomeCurrentPicBox);

            if (GameModel.HomeCellStatus(HomeCurrentPosition.Column, HomeCurrentPosition.Row) == Cell.cellState.WATER)
            {
                HomeCurrentPicBox.Image = Properties.Resources.scan;

                HomeLastPosition = HomeCurrentPosition;
            }

            gameFormToolTip.SetToolTip(HomeTableLayoutPanel, GameModel.alphaCoords(HomeTableLayoutPanel.GetCellPosition(HomeCurrentPicBox).Column) + "," + HomeTableLayoutPanel.GetCellPosition(HomeCurrentPicBox).Row);
        }
    }

    private void HomeTableLayoutPanel_MouseEnter(object sender, EventArgs e)
    {
        Point p = HomeTableLayoutPanel.PointToClient(Control.MousePosition);
        PictureBox HomeCurrentPicBox = (PictureBox)(HomeTableLayoutPanel.GetChildAtPoint(p));

        if (HomeCurrentPicBox != null)
        {
            TableLayoutPanelCellPosition HomeCurrentPosition = HomeTableLayoutPanel.GetCellPosition(HomeCurrentPicBox);

            if (GameModel.HomeCellStatus(HomeCurrentPosition.Column, HomeCurrentPosition.Row) == Cell.cellState.WATER)
            {
                HomeCurrentPicBox.Image = Properties.Resources.scan;
            }

            gameFormToolTip.SetToolTip(HomeTableLayoutPanel, GameModel.alphaCoords(HomeTableLayoutPanel.GetCellPosition(HomeCurrentPicBox).Column) + "," + HomeTableLayoutPanel.GetCellPosition(HomeCurrentPicBox).Row);
        }
    }

    private void HomeTableLayoutPanel_MouseLeave(object sender, EventArgs e)
    {
        if (GameModel.HomeCellStatus(HomeLastPosition.Column, HomeLastPosition.Row) == Cell.cellState.WATER)
        {
            HomeLastPicBox = (PictureBox)HomeTableLayoutPanel.GetControlFromPosition(HomeLastPosition.Column, HomeLastPosition.Row);

            HomeLastPicBox.Image = Properties.Resources.water;

            gameFormToolTip.SetToolTip(HomeTableLayoutPanel, GameModel.alphaCoords(HomeTableLayoutPanel.GetCellPosition(HomeLastPicBox).Column) + "," + HomeTableLayoutPanel.GetCellPosition(HomeLastPicBox).Row);
        }
    }

我以为我会为未来的知识寻求者发布解决方案。

感谢。
